The pulse width TH and the interpulse width TL can be provided by the actual value of another
already-programmed function:
Analog comparator: Ax – Ay
Analog trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Analog math: AQ
PI controller:AQ
Data latching relay: AQ
Up/Down counter: Cnt
The value of "TH","TL"can be set/modified in parameter mode.

Description of the function
With the change at input Trg to 1, the time T
L
(time low) is triggered. After the time T
L
has expired, output Q
is set to 1 for the duration of the time T
H
(time high).
If input Trg is retriggered prior to the expiration of the preset time (T
L
+ T
H
), the time Ta is reset and the
pulse/pause period is restarted.
If retentivity is not set, output Q and the time are reset after a power failure.
